The HRT F1 team is working '24/7' in a bid to roll-out its new car at Barcelona's Circuit de Catalunya this week.
Currently the Spanish outfit is hoping to arrive at the track on Saturday, with a view to doing some miles on the fourth and final day on March 4.
“We are working 24/7 to have everything ready for the tests,” HRT sources told Crash.net
“We want to get to Barcelona as soon as possible and get some mileage on the new car but when that will be is not confirmed yet. We think that, if everything works well, we can get there on Saturday to test on Sunday. Tomorrow or Friday we will know better.”
Pedro la Rosa and Narain Karthikeyan will drive for HRT this year, with the season opening Australian GP set to take place on March 18.
